Steampunk tattoos - the cousin of biomechanical tattoos, but with gears instead of cybernetic implants.
Steampunk is a fictional era reminiscent of Victorian times. People living in this period never went beyond steam engines; their technological development went towards mechanics instead of electronics. This resulted in a very interesting style that is hard to mistake for anything else. This trend is often included in alternative histories of humanity. Steampunk tattoos draw heavily from this, featuring mechanical limbs teeming with gears, cogs, and various transmissions.
